Be it known that I, EPI-IRAIM G. KLINE, a citizen of the United States ofy America, residing at Millerstown, in the county of Perry and. VState of Pennsylvania, have invented new and useful Improvements in Rim Construction, of which the following is a specification.

This invention relates to improvements in rim construction and has cation to a demountable tirecarrying rim for use in' connection with the wheels of motor vehicles.

In carryingout thepresent invention it is my purpose to provide a split rim wherein the ends of the rim may be quickly and convenientlyfbrought into overlapping relation in order to contract the rim so that the tire' may be removed therefrom andy a new tire or shoe placed thereon and wherein the ends of the rim at the splitl'may be easily and quickly moved to an abutting position in order to expand the riin sothat thetire on the rim will be securely and efectively held thereon. l

It is alsomy purpose to provide a rim structureof the character described wherein means for contracting and expanding the rim will embody comparatively few parte and being so arranged and correlated as to reduce the possibility of derangement to a minimum.

W ith the above recited objects in view and others of a similar nature the invention resides in the construction, combination and arrangement of parts set-forth inl and lfalling within the scopeof the appended claims.

In the accompanying drawing Figure 1 is a fragmentary side elevation of a rim constructed in accordance with my invention, the parts being shown inex panded position.

Fig. 2 is a similar view showing the parts in contracted position.

vFig.' 3 is a fragmentary longitudinal sec- 4tional View through the rim.

IFig. 4 is a cross sectional view through the same. l

Referring .now to the drawing in detail 1 designates a rim split transversely 'as at 2 and having the spl-it ends abutting 1 each other in a normal or expanded condition of the rim so that the inner tube and the casing of the tire will befsecurely andcffectively' held upon the rim. In the present instance articular appli- Y 10 whereby the particular dog may the side edges of the rim are provided with clencher flanges 3 and designed to engage 'the clencher beads on the tire tube or case to prevent accidental' removal of the tire case from therim.

In accordance withmy present invention. arms 4. are formed integral with the inner surface, of therim and oneend .of said `rim andthese arms' project toward and under the outer end portion of the rim and spaced yapart in parallelism as illustrated. ,Formed on the-inner surface of the other end portion ofthe rim4 is a longitudinal' row of teeth 5 arranged in line with the space between the armsA. Passed through the outer en'ds of the arms 4e is a'pin 6.' 7 designates a lever formed, adjacent to one end, with afsloil i through which the pin 6 passes iii-order to hold the lever fulcrumed between the outer ends of the arms 4i. One end portion ofthe lever 7 is adapted-to engage the teeth 5 while the other end portion oi' the lever is capable of being grasped by the hand so that the, lever may be manipulated to expand and contract the rim. Also pivotally mounted upon the pin (i at the oppositesides oi the lever are holding dogs or pawls 8 each equipped with a spring 9 acting to hold the dog in active position, and formed with an 'opening adapted to aline with.' a similar opening 'in one of the arms d to receive a pin in inactive position against the action ofthe spring 9. i

In practice, when the rim is in expanded condition the meeting ends thereof 'abut and the dogs 8-8 are held in a space between the arms 4 by means oi the pin 10, while the lever 7 is swung to a position to lie within thcplane of the arms 4. The arms and the lever are adapted to fit intov a cut outrecess'- in the felly of the wheel when the rim is placed on the wheel so that the rim may be effectively locked to the wheel to prevent accidental disconnection of the parts.

When it is desired to contract the rim, the dog 8 at the right hand side oi the lever ,7 in Fig. 2 of the drawing is relieved ont the holding influence of its pin 10 so that the spring 9 may react to throw the dog to active position. The lever 7 is now swung -to be held auA ico

an angle of 90 degrees more or less, and this pull the end bearing the arms- 4 downwardly and'on the inner sideof the other end portion'of the rim. Continued manipulation of the lever 7 throws'the arm bearing portion of the iiimfarther into the circle vdepicted by ther outer end portie# of the rim thereby l case r shoe may be c` veniently removed.

contracting the rim so tt theI tire tube and from the rim. The acti e dog 8, during the manipulation of ,the lever 7, engages the teeth 5 to prevent retrograde motion of the rim thereby preventing accidental expansion f the rim.

To expand the rim, the formerly active dog 8 is swung to inactive position and held -in siich positionby the pin 10, while the other dog is permitted to move to active position and the lever 7 manipulated in the reverse direction thereby expanding the rim.

' While I have herein shown and described one particular forni of my invention by'way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction y herein de- 'scribed and delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention. i
